Klebsiella pneumoniae strains co-producing klebsiella pneumoniae carbapenemase (KPC) and verona integron-encoded metallo-beta-lactamase (VIM) are frequently isolated in Greece and have also occurred in other European countries. Conventional combined disc tests exhibit low sensitivity against these emerging pathogens. We have evaluated modifications of the KPC/Metallo-β-Lactamase Confirmation ki...

OBJECTIVES To determine the distribution and heterogeneity of metallo-beta-lactamases (MBLs) responsible for imipenem resistance in Chryseobacterium meningosepticum. METHODS Clinical C. meningosepticum isolates (n = 170) were collected from hospitals in Hangzhou, China. Production of MBLs was investigated by determination of imipenem MICs, and by using both a three-dimensional test and a 2-me...

The main objective is to study the genotypic and characterization of plasmid deoxyribonucleic acid content resistant isolates in Erbil city. A total 39 Acinetobacter baumannii were isolated from 102 diabetic foot ulcer patients, whose ages ranged 37 88 y, attending various medical wards hospitals city, Iraq, between May 2020 March 2021. Isolates tested for presence extended-spectrum beta-lactam...

Background: Acinetobacter baumannii, is an opportunistic pathogen and is responsible for numerous nosocomial infections. In recent years, this microorganism has been resistant to a wide range of antibiotics. One of the most important mechanisms of resistance in this microorganism is production of metallo-beta-lactamases (MBLs). Objectives: The aim of this study was to detect VIM- and IMP-type ...

BACKGROUND Metallo-β-lactamases are bacterial enzymes that provide resistance to carbapenems, the most potent class of antibiotics. These enzymes are commonly encoded on mobile genetic elements, which, together with their broad substrate spectrum and lack of clinically useful inhibitors, make them a particularly problematic class of antibiotic resistance determinants. We hypothesized that there...

The aim of this study was to characterize two metallo-β-lactamases (MBLs)-producing Pseudomonas aeruginosa clinical isolates showing meropenem susceptibility. Antimicrobial susceptibility was assessed by automated testing and Clinical and Laboratory Standards Institute agar dilution method. MBL production was investigated by phenotypic tests. Molecular typing was determined by pulsed field gel ...

Introduction: Skin and soft tissue infections (SSTI’s) are commonly caused by both gram positive and gram negative bacteria. The aim of the study was to investigate the presence of methicillin resistant Staphylococcus aureus (MRSA), Extended Spectrum Beta Lactamase (ESBL), Amp C and Metallo β-lactamase producing gram negative bacilli from clinical isolates obtained from patients attending G.S M...
